Im new to GIS and this is for a class. I have shapefile (MEUSGSDATA) it has info on arsenic test results. the fields are TOWN (town names), COUNT (# of arsenic tests), AS_MEAN (mean arsenic test value in ppb) and AS_MAX ( maximum arsenic test value in ppb). I need to only include towns with maximum arsenic test values (AS_MAX).What would be the steps to take?

Hi there.. well.. you can go to the Definition Query tab in the layer properties.. and build a query... where you specify what you want... imagine that you want the towns with maximum arsenic test values over 1000.. so your query builder would be something like 'AS_MAX' > '1000'
